The ADP7104 is a CMOS, low dropout linear regulator that operates from 3.3 V to 20 V and provides up to 500 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from 19 V to 1.22 V rails. Using an advanced proprietary architecture, it provides high power supply rejection, low noise, and achieves excellent line and load transient response with just a small 1 μF ceramic output capacitor.

Low Noise: 15 μVRMS for fixed output versions
PSRR Performance of 60 dB @ 10 kHz at VOUT=3.3 V
Reverse current protection
Initial accuracy: ±0.8%
